I'm not getting any noise at all using a daisy chain to power a Mooer Tender Octaver, a Mooer Yellow Compressor and a Joyo American Sound (the latter via fx loop send/return).
However, a 'hum' appears when I add a Ditto x2 looper to the daisy chain - and the 'hum' is only slightly lower when I disconnect the Ditto from the daisy chain and plug it in via a separate power adaptor. Not sure whether this is significant, but the daisy chain and the separate adaptor connect to the wall socket via the same power strip.
And as I'll be adding a Neunaber Immerse, a Freeze, a Key9 and a wah, I'm assuming I need to get a special insulated power supply, too. The pedals are all 9v DC and all are 'True Bypass' (except the Neunaber, which has 'buffered bypass').
Most of the pedals are for fun/study; eventually, I'll put together a pedal board (perhaps the Pedaltrain Metro 24, which would take a CIOKS DC8). But, in the short-term, I'm looking for a cheap temporary solution.
Here's my question:
Would a combination of daisy chain for some pedals + 9v batteries for others work (i.e. not add noise)?
Thanks in advance!Last edited by destinytot; 12-15-2016 at 02:14 PM.

It probably needs an isolated DC-feed (although with the adapter in the same wall socket I would think that is isolated?!?).
What does it do when you run the Ditto on a battery and the rest on the daisy chain?
-
What you need to read up on are ground loops. You might need to clip the ground on one end of a audio connection for example. This has to be worked out for individual set ups.

I had a music stand lamp that was causing hum when I touched the stand and this removed the hum. It may work in your situation (but possibly not--the reviews in Amazon are hit or miss).

Interesting. You put it in the lamp or the amp?

I'll be following this thread. In my experience, loopers are noisy. And they kill batteries too fast to not use a power supply. I've just learned to live with it, but if you come up with a good fix I would love to hear it.
-
This might be overkill, but my EHX Humdebugger works great for stuff like this. I got a used one on CL for $65.

Prevention is best, for unpreventable noise, hard to beat ISP Decimator G-string II.

You might want to see if all the adaptors have the same +/- relationship on their plugs. One of them (I suspect the looper) may be out of synch, causing the ground loop. It's worth checking, at least. Good luck!
-
Seriously: no daisy chaining, no cheap power supplies, no cheap patch cables. A good isolated power supply (Cioks mentioned) is the only way, everything else is more or less waste of money.
But then of course, every body spends their money how they want!
And if You use two amps, then Lehle boxes are the hum killers.

I've just set up to play; the Mooer Yellow Compressor and Mooer Tender Octaver each have their own mains adaptors, while the Joyo American Sound (going through fx loop send/return) and the Dittox2 looper are running on batteries - completely noise-free! I'll try and get a waiter to film a bit on my mobile later. Originally Posted by Little Jay

Thanks all!

Get some Lithium 9 V batteries or get a used Sanyo Pedal Juice, make sure you don't forget it plugged in though Originally Posted by destinytot

I bought one of these (EbTech Hum-X) almost a year ago and ALWAYS play with the amp plugged into it. It makes a big difference in my case. Originally Posted by blille

i have a noise gate (te electronic sentry) that is ok. it eats up too much tone before it solves my problems, or does it unnaturally. so it sits behind my favorite pedal to clean up noise, the empress buffer plus (strangely enough) at a lighter setting. then maybe i'll turn up the sentry if using a lot of gain or whatever. the empress does very very little to change the tone, but since my room is bad, it doesn't go quite far enough. empress offered to change a few values to give me that extra bit, but i haven't taken them up on that yet. maybe one day.
that worked for a while but then i started getting noise from the dimmer switches from the lights in my room- i high pitched whine to go along with the lower end buzzing. the simplest and easiest solution was to just get a denoiser plug in and use that when i'm recording. the analog solutions i tried were complicated and unsuccessful- lots of trial and error with gadgets, magnets and ferrite. i may eventually go back and do it "the right way" but it works for now so screw it.

Came across this 'pedal' (?) while watching videos about 60 cycle hum - not at all practical, but very beautiful (and the technology is fascinating):

Looking into the Sanyo Pedal Juice, it seems to be available new for under 50 euros. Originally Posted by medblues

And one of the comments on the video makes this claim: "Sometimes, you get hum or noise from the power socket. Batteries, never. As long as you regularly charge them, you have zero issues."
Could it be that all I need is to connect the daisy chain of pedals to one of these rechargeable batteries (rather than to a mains socket) to keep them working quietly? That would be great! Thanks in advance!

Yes - if you are going to use batteries, rechargeable is the way to go. I was an early adopter of the Rockman back in the day, before the ac adapter for it was available. In the first year I spent more on batteries than for the Rockman itself, which was not cheap. It was just the ticket for a band that played pop, rock, country, western, blues, jazz, polkas - you name it. We gigged a good bit.

I have an ESA lithium-ion battery, 9V/5400mAh, that I bought years ago to power something, I forget what. I never used it much, and it sat around, until I decided to use it for the HOF Mini that I bought. I don't know how long it will power the Mini, but I charge it weekly, mostly, and I've never run it down. The only downside was that the output is center positive, and most pedals, including the HOF mini, are center negative. It's easy enough to rig up a cable with the polarity reversed, though. Very handy for places where you don't have easy access to enough power outlets, and zero noise. I don't use standard 9V batteries very much.

I've often wondered what these symbols mean - thanks, guys!

I've often wondered why pedals generally use center negative, while the rest of the world uses center positive. Adapters with center negative tips are rare outside the world of pedals.
